CASH REGISTER.

Application filed March 11., 1924. Serial No. 698,436.

This invention relates to cash registers and more particularly to cash registers of the type described in the patent to Kettering and Chryst, No. 1,137,061, issued April 27, 1915, to which reference may be had for a complete description of such parts of the machines as do not relate directly to the present invention.

An object of this invention is to provide means to prevent movement of the cash drawer to accessible position so long as its operating mechanism remains in home position.

A further object is to provide means to prevent opening the cash drawer prior to the time the full stroke mechanism becomes effective.

It is an object to positively preclude the opening and subsequent closing of the cash drawer without operation of the various registering and recording mechanisms, etc., with which the register may be equipped.

With these and incidental objects in view, the invention consists of certain novel features of construction and combinations of parts, the essential elements of which are set forth in appended claims and a preferred form of embodiment of which is hereinafter described with reference to the drawings which accompany and form part of this specification.

Of said drawings:

Fig. 1 is a right side elevation with the cash drawer shown in section, several parts of the mechanism being omitted for clearness.

Fig. 2 is a transverse vertical section of the machine, with parts of the mechanism omitted for clearness.

The machine illustrated in the above mentioned patent is of the drawer-operated type, that is, the energy for driving the mechanism during the opening movement of the cash drawer is stored up by the closing movement of the said drawer. The drawer is normally spring-pressed outward, but is restrained from such movement by a latch which is freed to release the drawer upon the depression of certain keys in the machine.

The drawer then opens under spring action and is returned by hand to its closed position. Upon the return movement of the drawer, the amount, clerks initial, transaction character, etc., set up on the keyboard are recorded on a record strip.

Referring to the drawings, only so much of the mechanism is shown as is necessary to clearly illustrate the improvement, the complete mechanism being shown in the Kettering and Chryst patent previously referred to.

The machine is operated in the usual man ner by depressing the proper keys representthe transaction, after which a release bar 30 (Fig. 1) is operated to release. the cash drawer 31 and cause the operation of the machine. The release bar 30 is secured to a forked plate 32, suspended by links 33 and 34 supported on the frame member 35. This release bar is retained in normal posi tion by a spring 36. A pin 37 mounted in a bell crank lever38 pivoted at 39 is held in engagement with the plate 32 by a spring 40 stretched between the pin and a pin in the plate 32. This causes the bell crank lever 38 to move when the release bar is operated. The lower end of the bell crank lever 38 is formed with two notches 41 and 42. which are engaged by a roller 43 on a rod carried by arms 44 and 50 pinned on a rod (Figs. 1 and 2). A link 51 connects the arm to a drawer latch 52 pivoted at 53 to the frame of the machine. lower end. of the latch 52 is bifurcated to receive a roller 54 carried in the bracket mounted on the rear end of the cash drawer. The roller 43 engages the notch 41, as shown in Fig. 1. to hold the latch in the position shown in Fig. 2, thereby preventing opening movement of the drawer. WVhen the release bar is pushed, the roller 43 is freed from the notch. 41, thereby permitting the latch 52 to swing and the drawer to open. The latch is held in .its moved position bya spring stretched between the link 51 and a member rigid with the left side frame.

Then the latch 52 is freed to move clockwise, a pair of drawer-operating arms 55, mounted on studs 56 on opposite sides of the machine, one arm being shown in Fig. 1, are swung clockwise to move the cash drawer forward. These arms are actuated by a spring 57 (Fig. 2) attached to the frame of the machine and to an arm 58 pivoted on a rod 59 supported in the side frame. The arm 58 is connected by a link 65. to a bell The crank lever 66 which is pinned to a rod 67.

As only the right hand arm of the pair of arms 55 and its associate partslare shown, the description will refer to such parts roller 71 which engages a block 72 secured to the cash drawer 31. Also fast on the lower I end of the drawer-operating arm is a springactuated full-stroke pawl 73 which cooper- 1 ates with notches in a rack plate 74 to compel the drawer-operating arms to be moved I forward the proper distance before the cash drawer can be-returned to its normal position.

means fordriving the machine, as well as meansfor storing up energy in the spring 57 as theyare-moved counter clockwise by theclosing movement of the cash drawer as 2 is fully explained inthe patent previously referred to.

A link 7 5 connects the lower end of the -bell crank lever 66 with a member 76 pivoted on a stud 77; This member is connected bya pin 78 to a printer writing table 79,

i also pivoted on the stud 77. The complete printing mechanism is not shown here. as it is fully illustrated and described in the patcut to Chryst- No. 1.140.443 issued May 25.

shown as is deemed necessary vproperly to set forth the invent-ion.

The totalizer 85 is supported by a pair of arms 86 pinned to a rod 87, and is normally in engagement with an actuator 88 mounted on a segment 89 pivoted oira stud supported by a keyframe and in axial alinement with a stud 90 supported in the side frame of the machine. The segment is actuated in one direction by a spring by which it is held against a 'rod 91 supported by a pair of arms 92 actuated by a pair of plates 94pinned to the rod 67; only one arm 92 and plate 94 being shown. The plates 94- are provided with cam slots 93co0perating with rollers onthe arms 92: As the arms 92 are moved counterclockwise, the, segment 89 will assume. posi tions corresponding to an item key de-' pressed, representing thetransaction to be recorded. after which the segment 89, will i be returned to its normal position by the ;rod 91, all of which isclearly illustrated and described in the; Kettering andChryst pat-J ent previouslyreferred to.

As the drawer operating arm 55swins1's forward about its pivot 56 the cam' plate 111 will cause the bell crank lever 103 and its connecting parts to rock the rod 87 to disengaa'e the totalizer from its-actuators. As the drawer operating arm approaches its forward position, the cam plate 111 will enga a roller 114 carried on the bell crank lever 100 and rock this lever clockwise. and cause I drawer operating arm 55 to its normalposi tion, the cam plate 111, as it engages the roller 110, will be moved in a clockwise direction against the tension of its spring until the arm 55 reaches a point where the cam plate'lll will clear the roller 110,, when the spring 113 will return the plate to its normal'position so that the cam plate 111 ,will not move the bell crank lever 103 counterclockwise, as the arm 55'returns to its home position.

For the purpose of maintaining the totalizer in engagement with theactuators on the return movement of the arms 55 and at the time the cam plate 111 engages the roller 1.10, a lever 115 pivoted at 116 to the rack plate 74 and lying in the plane of the bell crank lever 103, has an upwz'irdly ext-ending projection engaging a downwardly extending projection on the bell crank lever. The lever 115 is held rigid at this time by a pin 117 mounted in the full-stroke pawl 73engaging the lower edge of the lever. A spring 118 holds the lever 115 in its normal position with a laterally projecting lug 119, engaging the top side of an opening 120 formed in an arm 121 pivot-ed on a stud 122 supported in the rack plate 7 lie?) the lever is moved clockwise by the forward movement of the drawer operating arm on the right side of the machine, the arm 121will he raised to .place the right hand end 123 out of the path of a bracket 121, which is secured to the cash drawer 31. The function of the arm 121 and the bracket} 12 1 is to intercept the cash drawer after it released. it pressure is V I v iting table 79 (Fig. 2) to hold back the drawer operating aclr plate After the pawl L' p first notch, it is necessary to complete the operation ot the mechanism and the proper records of the transaction before the drawer can be returned to its inaccessible position. l Vithout this device, it would be possible to have access to the cash drawer without the proper operation of the machine.

This was accoumlished by holding the writing table against movement. Through the connecting mechanism this would prevent the drawer operathig arms from. mov ing far enough for the full stroke device to become ell ective, and therefore as the drawer had been released it could move forward, money could be removed therefrom, and it could be closed again without making any record whatever on the detail. strip or the totalizer, As aiovc noted, with the present invention in use, it the writing table is held after the rel case oil? the machine, the bracket 1% will strike the rear end 12?) of arm 121 and will prevent the openii of the drawer.

The operation of? the demos during the proper operation of the machine is as follows: its the motor bar is operated to release the cash drawer and the drawer operating arms swing forward, the cam plate 111 engaging the roller. 110 will move the bell crank lever 10?- counter-cloclrwise and the lever 115 clockwise which will elevate the end 123 oi": the arm 121 out of the path of the bracket 124: mounted on the cash drawer. As the cash. drawer is returned to its home position the bracket 12-5 will engage the angle edge of the end 123 of arm 121 and slightly raise the arm as the bracket passes under the same.

lVhile the form of mechanism herein shown and described is admirably adapted to fulfill the objects primarily stated, it is to be understood that it is not intended to conline the invention. to the one form of embodiment herein d sclosed, for it is susceptible of embodiment in various forms all coming within the scope of the claims which follow.
